Subject [jira] [Created] (HADOOP-13421) Switch to v2 of the S3 List Objects API in S3A
Date Mon, 25 Jul 2016 21:49:20 GMT
Steven K. Wong created HADOOP-13421:

             Summary: Switch to v2 of the S3 List Objects API in S3A
                 Key: HADOOP-13421
                 URL: https://issues.apache.org/jira/browse/HADOOP-13421
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/s3
    Affects Versions: 2.8.0
            Reporter: Steven K. Wong
            Priority: Minor

Unlike [version 1|http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketGET.html] of the
S3 List Objects API, [version 2|http://docs.aws.amazon.com/AmazonS3/latest/API/v2-RESTBucketGET.html]
by default does not fetch object owner information, which S3A doesn't need anyway. By switching
to v2, there will be less data to transfer/process. Methods in S3AFileSystem that use this
API include:

* getFileStatus(Path)
* innerDelete(Path, boolean)
* innerListStatus(Path)
* innerRename(Path, Path)

Requires AWS SDK 1.10.75 or later.
